Johnson said the Web site Texas Watchdog gave his office a list of 4,000 names of possible dead voters created by comparing the registration list against Social Security documents. He said they are reviewing the list.

But Johnson said Texas Watchdog gave the list to a Houston television station that found two people on the list had voted in the 2008 primary. He said the family members were upset to find their relatives’ identity had been stolen.

Johnson said the cases were turned over to the district attorney’s office, but there was not enough evidence to know who cast the ballots

Johnson said there was another attempt to register 121 people in 2006 at a non-existent address on Dashwood Street. He said the applications were mailed in from El Paso. The case is still under investigation.

In a third case, a college student who had a voter registration project in class in 2000 made up 61 registration applications and filed them. Johnson said she was prosecuted.
